Cisco AnyConnect Secure Mobility Client for Windows with VPN Posture (HostScan) Module DLL Hijacking Vulnerability

A vulnerability in the interprocess communication (IPC) channel of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed on the AnyConnect client. This vulnerability is due to insufficient validation of resources that are loaded by the application at run time. An attacker could exploit this vulnerability by sending a crafted IPC message to the AnyConnect process. A successful exploit could allow the attacker to execute arbitrary code on the affected machine with SYSTEM privileges. To exploit this vulnerability, the attacker needs valid credentials on the Windows system.

golang.org/x/crypto: Processing of crafted ssh-ed25519 public keys allows for panic

golang.org/x/crypto before v0.0.0-20200220183623-bac4c82f6975 for Go allows a panic during signature verification in the golang.org/x/crypto/ssh package. A client can attack an SSH server that accepts public keys. Also, a server can attack any SSH client.

HUAWEI P30 with versions earlier than 10.1.0.135(C00E135R2P11) have an improper signature verification vulnerability. The system does not improper check signature of specific software package, an attacker may exploit this vulnerability to load a crafted software package to the device.

exacqVision Software - Improper Verification of Cryptographic Signature

A vulnerability exists that could allow the execution of unauthorized code or operating system commands on systems running exacqVision Web Service versions 20.06.3.0 and prior and exacqVision Enterprise Manager versions 20.06.4.0 and prior. An attacker with administrative privileges could potentially download and run a malicious executable that could allow OS command injection on the system.

A vulnerability was reported in LenovoAppScenarioPluginSystem for Lenovo System Interface Foundation prior to version 1.2.184.31 that could allow unsigned DLL files to be executed.

A wrong generation of the passphrase for the encrypted block in Nextcloud Server 19.0.1 allowed an attacker to overwrite blocks in a file.

In JetBrains Rider versions 2019.3 EAP2 through 2019.3 EAP7, there were unsigned binaries provided by the Windows installer. This issue was fixed in release version 2019.3.

TUF (aka The Update Framework) through 0.12.1 has Improper Verification of a Cryptographic Signature.

Signature Wrapping Vulnerability with spring-security-saml2-service-provider

Spring Security versions 5.2.x prior to 5.2.4 and 5.3.x prior to 5.3.2 contain a signature wrapping vulnerability during SAML response validation. When using the spring-security-saml2-service-provider component, a malicious user can carefully modify an otherwise valid SAML response and append an arbitrary assertion that Spring Security will accept as valid.

python-pysaml2: does not check that the signature in a SAML document is enveloped

PySAML2 before 5.0.0 does not check that the signature in a SAML document is enveloped and thus signature wrapping is effective, i.e., it is affected by XML Signature Wrapping (XSW). The signature information and the node/object that is signed can be in different places and thus the signature verification will succeed, but the wrong data will be used. This specifically affects the verification of assertion that have been signed.

Cisco IOS XE Software Digital Signature Verification Bypass Vulnerability

A vulnerability in software image verification in Cisco IOS XE Software could allow an unauthenticated, physical attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability is due to an improper check on the area of code that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device.

Union Pay up to 3.3.12, for iOS mobile apps, contains a CWE-347: Improper Verification of Cryptographic Signature vulnerability, allows attackers to shop for free in merchants' websites and mobile apps, via a crafted authentication code (MAC) which is generated based on a secret key which is NULL.

Union Pay up to 3.4.93.4.9, for android, contains a CWE-347: Improper Verification of Cryptographic Signature vulnerability, allows attackers to shop for free in merchants' websites and mobile apps, via a crafted authentication code (MAC) which is generated based on a secret key which is NULL.
